JACK.

Application filed. Uetober 20, 1925. serial No. 63,718.

This invention relates to a jack designed primarily for use in connection with vehicle wheels, one of the objects of the invention being to provide a simple and compact device of this character adapted to be securely fastened in a novel way, to a wheel after which, by rotating the wheel, the jack will be carried therewith and will be brought in a position to lift the wheel oil of the ground and support it in its raised position.

Another object is to provide a ack having means for attaching the same securely to a wheelwithout requiring the use of any tool or tools other than a' wrench.

Another object is to provide a jack of this type which can be adjusted to fit wheels of different diameters and which can be applied to wheels having brake drums connected thereto.

Another object is to provide a jack which, while in engagement with the supported wheel will not interfere with the easy removal and replacing of a tire.

With theloregoing and other objects in view which will appear as the description proceeds the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings,

Figure 1 is side elevation of a portion of an automobile wheel showing the jack plied being s applied thereto and in use.

Figure 2 is a front elevation of the jack, a portion of the wheel to which it is apiown in section.

a section on line 33 Fig- Figure 3 i ure 2.

Referring to the figures by characters of reference 1 designates the base or foot of the jack provided, at its ends, with upwardly inclined portions 2. Extending upward- 1v from this shoe is a socket member 3 for the reception of a tongue l which constitutes a continuation of the web portion 5 of a standard '6. This standard, in addition to the web portion 5, has oppositely extending flanges 7 at the edges of the Web. Tongue 4 is secured in the socket portion 3 by means which is straddled by the "forked end 13 of a screwthreaded shank 1 1, this forked portion being held on the arm 12 by a rivet or the like. A sleeve 15 is slidably mounte; on each threaded shank 15 and is provided, at its upper end, with a tapered head or enlargement 16. formed within each sleeve and extending radially from each of the shanks 14; is a guide pin 18 extending into the slot in the sleeve on said shank. A nut 19 engages each shank 14 and is adapted to bear against the lower end of the sleeve 15 on said shank.

In practice the nuts 19 are adjusted downwardly on the shank 14 after which the arms 12 are placed at opposite sides of one of the spokes S of the wheel to be lifted. The standard 6 is then adjusted outwardly relative to the wheel so that the telly or rim portion of the wheel will be seated within the two recesses with the stop 11 pressed against the inner side of the engaged spoke. Sleeves are then slid longitudinally along the shank l l until their heads or enlargements 16 become wedged between the adjoining spokes. Nuts 19 are screwed longitudinally against the shank until they come against the sleeves and by tightening these nuts they will force the heads of the sleeves firmly into the crotches between the spokes.

Thus the jack will be attached securely to the wheel. The wheel can now be rotated and this will cause one of the inclined ends 2 of the base or foot to come against the surface of the ground after which the inter mediate portion of said base or foot will engage the ground and support the standard in an upright position with the wheel el vated siown in Figure 1.

it will be apparent that the jack herein described can be used on the inner side of a wheel whether or not the same is provided with a brake drum. By having the longitudinally adjustable sleeves 15 the jack can A longitudinal lot 17 is ltlO carried by said laterally extending means for wedging between the spokes otthe eniged wheel.
